TRIGGER ATTACHMENT FOR FIREARMS.

Application filed May 17.

T0 all 107mm it 'may concern: p

Be it known that I, EUGENE T. TimursoN, a citizen of the United States, residing at Tiffin, in the county of Seneca and State of Ohio, have invented certain new and useful Improvements in Trigger Attachments for Firearms, of which the following is a specification.

My invention relates to an improvement in trigger attachments for firearms.

' The purpose is to provide for the pulling of the trigger to discharge the firearm without in any way interfering with the accuracy of the aim which often results from the pulling of the trigger.

This invention consists in a spring-actuated plunger slidably mounted and which when released strikes the trigger with sufiicent impact to discharge the firearm, thus avoiding a pull upon the trigger which so often seriously affects the aim.

In the accompanying drawings:

Figure l is a fragmentary side elevation:

Figure 2 is a vertical section:

Figure 3 is a transverse section:

Figure 4 is a plan view of the guide bar:

Figure 5 is a view in end elevation of the plunger looking toward the left:

Figure 6 is a rear view of the trigger:

Figure 7 shows the device applied to a gun having a shell extractor:

Figure 8 is a longitudinal section through the attachment shown in Figure 7:

Figure 9 is a plan view of the same: and

Figure 10 is an end view of the plunger.

A represents the firearm which in this instance happens to be a repeating rifle, 1 is the usual trigger pivoted at 2, and, I- is the trigger guard.

A bar 4 which may be round, square or oval, is secured in any approved manner within the trigger guard so as to extend lengthwise thereof as viewed in Figure 1, one end 5 extending into a hole 6 in the forward end of the trigger guard, and the entire bar being passed through a hole '7 at the rear end and held in position by a pin or screw 8 or some similar means passed through the rear end of the bar to hold the latter in the trigger guard as shown in Figure l.

A plunger 9 preferably more or less conical is slidably mounted on the bar and has a lever 10 screwed or otherwise secured therein with its inner end fitted to or slidable in a V-shaped groove 11 extending 1923. :serial No. 639,582.

longitudinally of the bar 4. A spiral spring 1.2 sleeved upon the bar at, as shown in Figure 1, exerts spring pressure backwardly upon the plunger. An arrow head notch 13 extends on either side of the groove and presents two shoulders against which the sharp inner end 14 of the lever 10 is adapted to be held when the plunger slid forward and locked, by rocking the lever 10 to the right or left as shown in dotted lines in Figure 3 whereby to fasten it in position to strike the trigger 1 by pushing the lever aside to the intermediate position, either to the right or left as the case may be, until its sharp lower end 14 is removed from the shoulder and takes position within the groove, as shown in F igures 2 and 3, which action takes place when the gun is to be fired, the operator first taking aim and then pushing the lever 10 to the central position which can be done without moving the firearm a hairs breadth.

Screw 15 is used as a stop just in frontl of the arrow head notch 13 to limit the forward slide of the plunger.

In Figures 7 to 10 substantially the same device is shown as applied to a shell extracting rifle or gun. In this instance, a hollow barrel 17 is fastened in the hinged trigger guard and a plunger 18 is slidably fitted therein. The lever 20 of the plunger extends through a slot 19 and a notch 21 is provided at the forward end of this slot as a means for fastening the plunger as hitherto described in connection with Figures 1 to 5. A spring 16 in the forward end of the barrel 17 is in position to exert pressure upon the plunger.

In operating the firearm, it is loaded and cocked in the usual manner whereupon the operator pushes the plunger forward to the right or left and the gun is then ready to be fired. On taking aim instead of pulling the trigger as is customary the end of the lever 10 or 20 is pushed to the center whereupon the spring ca-uses it to slide and hit the trigger with sufficient impact to discharge the firearm.

IVhat I claim is:

1. A trigger attachment for firearms including a trigger, a trigger guard, a springactuated plunger rotatably and slidably mounted within the guard in position to strike the trigger when released.

2. A trigger attachment for firearms including a trigger, a guard, means within the guard extending inthe direction of, the trigger, a plunger having slidable oonnection with said means, and a spring for forcing the plunger when released against the trigger whereby to discharge the firearm.

3. A trigger attachment for firearms iuoluding a trigger, a trigger guard7 means secured to the guard, said means having a longitudinal slot with a notohl at the forward end, a plunger having slidable rotatable connection with the means, and a spring adapted to be Compressed by the plunger When held by the notch and exert-i its force against. the plunger to slide thel latter upon seid means When released from the notch 'whereby toy strike the trigger and discharge the lirearrn.

4l. A trigger attaolunentI for iirearins in- @hiding a trigger, a trigger guard, means connected with the guard and having a longitudinal, slot. Awith a notch at the forward end thereof, a spring-actuated plunger having slidable connection with said means and in position to actuate the trigger when released, and meansA connectedv with the plunger adapted to enter the notch and hold the plunger in its foi-Ward position.

In testimony whereof l atlix my signature.
